Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen-rich water preparation, and in particular relates to a system for preparing hydrogen-rich bath water. Background Art

[0002] As the role of hydrogen is continuously scientifically confirmed, hydrogen health and hydrogen beauty are gradually becoming popular. For example, the therapeutic effect of hydrogen-rich bath water is becoming more and more widely known. Bathing with this hydrogen-containing water can help remove harmful free radicals from the human body, slow down skin aging, activate cells, expel toxins from the body, promote blood circulation, and remove dirt, whiten and cleanse the skin.

[0003] The therapeutic effect of hydrogen-rich bath water is not only related to the hydrogen content in the water, but also to the size of the hydrogen bubbles in the water. Generally speaking, the more hydrogen content in the water and the smaller the size of the hydrogen bubbles, the more conducive it is for the hydrogen-rich bath water to exert its therapeutic effect. However, the hydrogen bubbles in the hydrogen-rich bath water prepared by the current preparation system have a larger diameter, which affects the therapeutic effect of the hydrogen-rich bath water. In addition, the hydrogen content in the hydrogen-rich bath water prepared by the existing preparation system is low, which is not conducive to the hydrogen-rich bath water to exert its therapeutic effect.

[0013] Furthermore, a circulating water pipe is provided between the degassing tank and the water tank.

[0014] Furthermore, the hydrogen generator includes an electrolytic cell and a DC power supply arranged outside the electrolytic cell.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention provides a water-gas mixing device for mixing water and hydrogen, and mechanically cuts the water and hydrogen entering the water-gas mixing device using spiral blades, so that large-diameter hydrogen bubbles in the water are dispersed into bubbles with smaller diameters, thereby reducing the diameter of the hydrogen bubbles in the water.

[0021] 2. The present invention arranges a first permanent magnet fixed on the inner wall and a second permanent magnet fixed on the rotating shaft in the water-gas mixing device, magnetizing the water flowing through and providing an alternating magnetic field at the same time, so that the magnetized water flow and the alternating magnetic field produce a magnetic resonance effect, decomposing the hydrogen bubbles in the water into hydrogen bubbles with smaller diameters, further reducing the diameter of the hydrogen bubbles in the water.

[0022] 3. The present invention adds an ejector at the inlet of the water-gas mixing device, so that the water and gas entering the water-gas mixing device are pre-mixed to form a strong jet flow, which is conducive to the mechanical cutting of the water and gas by the blades to form hydrogen bubbles with smaller diameters. Since the rotation of the blades in the water-gas device forms a slight negative pressure at the inlet, it is conducive to the increase of the pressure energy of water and gas in the diffusion chamber of the ejector, making the water-gas jet flow ejected by the ejector stronger, which in turn helps the blades to cut water and hydrogen, and further reduces the diameter of the hydrogen bubbles.

[0023] 4. The hydrogen generator of the present invention adopts electrolysis to produce hydrogen, and the hydrogen generated by the cathode electrode is transported away with water as a carrier, so that the hydrogen bubbles are just precipitated and formed at the cathode electrode and are carried away by the flowing water flow, thereby reducing the aggregation of hydrogen bubbles, and generating small-diameter hydrogen bubbles by electrolysis, thereby reducing the generation of large-diameter hydrogen bubbles, and reducing the diameter of hydrogen bubbles in the hydrogen-rich water after treatment by the water-gas mixing device.

[0024] 5. When preparing hydrogen-rich bath water, the present invention sets a degassing tank, so that the water entering the water-gas mixing device is degassed by the vacuum of the degassing tank, so as to remove the dissolved gas in the water, thereby increasing the amount of hydrogen dissolved in the water, and further improving the therapeutic effect of the hydrogen-rich bath water. At the same time, since the degassed water avoids the molecular interaction between the dissolved gas molecules and the newly added hydrogen gas molecules, the newly added hydrogen can be dissolved more in the water, thereby further increasing the dissolution of hydrogen in the water, and further increasing the amount of hydrogen dissolved in the hydrogen-rich bath water.

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] like Figures 1 to 4As shown, a system for preparing hydrogen-rich bath water includes a water tank 6 for providing a water source, a hydrogen generator 5 for providing hydrogen, and a water-gas mixing device 3 connected to the water tank 6 and the hydrogen generator 5 by pipelines. Water and hydrogen are fully mixed in the water-gas mixing device 3 to complete the final preparation of the hydrogen-rich bath water. The water-gas mixing device 3 is provided with a hydrogen-rich water pipe 1 for discharging hydrogen-rich water. The hydrogen-rich water pipe 1 is used to be connected to a bathing device, on which a pressure gauge 102 and a regulating valve 101 for flow regulation can be provided. The bathing device can be a bathtub or a shower. The water-gas mixing device 3 includes a shell 301, which can be a rectangular box-shaped or hollow cylindrical shape. A rotating shaft 302 driven by a driving motor 307 fixed on the shell 301 is provided in the shell 301. The rotating shaft 302 can be fixed to the output shaft of the driving motor 307 through a coupling, and a sealing ring is provided at the position passing through the shell 301 to avoid possible air leakage and water leakage. Specifically, the driving motor 307 can adopt a speed-regulating motor to facilitate the adjustment of the rotation speed of the rotating shaft 302. A spiral blade 303 is fixed on the rotating shaft 302, and an inlet 304 for entering water and air into the shell 301 is provided on the side wall of the shell 301 corresponding to the blade 303. An outlet 308 is provided at one end of the shell 301 away from the inlet 304. Water and hydrogen entering the shell 301 through the inlet 304 flow out of the outlet 308 after being stirred by the blade 303.

[0032] When in use, the drive motor 307 is started, and the drive motor 307 drives the rotating shaft 302 to drive the blades 303 to rotate, mechanically cutting the water and hydrogen entering the shell 301, so that the hydrogen bubbles in the water are dispersed into smaller bubbles, which helps the hydrogen-rich bath water to exert its therapeutic effect.

[0033] When implementing the present invention, a second permanent magnet 306 is also fixed on the rotating shaft 302. Specifically, the spiral blade 303 can be fixed on the upper half of the rotating shaft 302, and the second permanent magnet 306 can be fixed on the lower half of the rotating shaft 302. A first permanent magnet 305 is provided on the inner wall of the shell 301 opposite to the second permanent magnet 306. An inlet 304 for water and air intake is provided on the side wall of the shell 301 corresponding to the blade 303. An outlet 308 is provided at one end of the shell 301 away from the inlet 304. Water and hydrogen entering the shell 301 through the inlet 304 are discharged through the blade 303. 3, flows out of the outlet 308 along the channel between the first permanent magnet 305 and the second permanent magnet 306. Specifically, the first permanent magnet 305 and the second permanent magnet 306 can be arranged in multiple groups at equal intervals, that is, multiple second permanent magnets 306 are fixed at equal intervals on the lower half of the rotating shaft 302. Correspondingly, multiple first permanent magnets 305 are arranged at equal intervals on the side wall of the shell 301, and the number of the first permanent magnets 305 and the number of the second permanent magnets 306 are arranged one by one to enhance the strength of the magnetic field effect on the water carrying hydrogen flowing through the first permanent magnet 305 and the second permanent magnet 306.

[0034] When the driving motor 307 drives the rotating shaft 302 to rotate, the second permanent magnet 306 rotates with the rotating shaft 302, and the second permanent magnet 306 and the first permanent magnet 305 rotate relative to each other, generating an alternating magnetic field. When the water containing microbubbles flows along the channel between the first permanent magnet 305 and the second permanent magnet 306, the water flow is magnetized, and the magnetized water flow can produce a magnetic resonance effect with the alternating magnetic field, so that the hydrogen bubbles in the water are decomposed into hydrogen bubbles with smaller diameters, thereby further reducing the diameter of hydrogen bubbles in the water and improving the therapeutic effect of the hydrogen-rich bath water. In addition, the internal energy of the magnetized water is affected by the magnetic field, so that the water has a stronger gas dissolving ability, which can increase the dissolution of hydrogen in the water.

[0035] Furthermore, an ejector 4 is provided between the water-gas mixing device 3 and the water tank 6, and the ejector 4 includes a conical nozzle 405 connected to the water tank 6 pipeline, a drainage chamber 404 arranged outside the nozzle 405, a straight pipe-shaped mixing chamber 402, and a trumpet-shaped diffusion chamber 401 connected to the inlet 304. The nozzle 405, the drainage chamber 404, the mixing chamber 402 and the diffusion chamber 401 are sequentially connected along the water flow direction, that is, the nozzle 405, the drainage chamber 404, the mixing chamber 402 and the diffusion chamber 401 are integrally arranged, and the drainage chamber 404 is provided with a pipe connected to the hydrogen generator 5. The drainage pipe 403 is connected to the drainage chamber 404, and the drainage chamber 404 covers the nozzle 405. The hydrogen from the gas generator 5 enters the drainage chamber 404 through the drainage pipe 403. When in use, the nozzle 405 sprays water at a certain pressure and speed. The water passes through the drainage chamber 404, the mixing chamber 402 and the diffusion chamber 401 in sequence and enters the water-gas mixing device 3. A local vacuum is generated in the mixing chamber 402. The hydrogen entering the drainage chamber 404 through the drainage pipe 403 forms a large number of tiny bubbles in the process of being sprayed along the diffusion chamber 401 under the water spraying pressure, which is conducive to the water-gas mixing device 3 to produce hydrogen bubbles with smaller diameters.

[0036] At the same time, when the ejector 4 sprays water and gas into the water-gas mixing device 3, the kinetic energy of the water and gas in the diffusion chamber 401 is converted into pressure energy to form a strong jet flow, and the blades 303 in the water-gas mixing device 3 will form a slight negative pressure at the inlet 304 of the shell 301 when rotating, which is beneficial to the increase of the pressure energy of water and gas in the diffusion chamber 401, and then helps the hydrogen bubbles to be cut by the blades 303 after entering the water-gas mixing device 3, thereby further reducing the diameter of the hydrogen bubbles.

[0037] Furthermore, when the amount of hydrogen entering the drainage pipe 403 is large, the water outlet of the water-gas mixing device 3 may contain large hydrogen bubbles. These large hydrogen bubbles cannot play a therapeutic role during the use of the bath water, and are wasted with the use of the hydrogen-rich bath water. Accordingly, a gas-liquid separator 2 for separating and recovering large bubbles in the water flowing out of the outlet 308 can be provided outside the water-gas mixing device 3. The liquid inlet of the gas-liquid separator 2 is connected to the outlet 308 pipeline, the exhaust port of the gas-liquid separator 2 is connected to the drainage pipe 403 pipeline, the hydrogen-rich water pipe 1 is connected to the discharge port of the gas-liquid separator 2, and the gas-liquid separator 2 can be The cyclone separator may also be an expansion container whose pipeline size is appropriately larger than the diameter of the hydrogen-rich water pipe 1, that is, the gas-liquid separator 2 may use cyclone separation or a sudden drop in pipeline pressure to separate large bubbles in the water from the water. The exhaust port of the gas-liquid separator 2 is connected to the drainage pipe 403, and the hydrogen-rich water pipe 1 is connected to the discharge port of the gas-liquid separator 2. In specific applications, a bypass bypassing the gas-liquid separator 2 may be provided between the hydrogen-rich water pipe 1 and the outlet 308, so that when the amount of hydrogen entering the drainage pipe 403 is small, the hydrogen-rich bath water may be directly discharged from the hydrogen-rich water pipe 1, without having to pass through the gas-liquid separator 2 to be discharged from the hydrogen-rich water pipe 1.

[0038] When the gas-liquid separator 2 is put into use, the large bubbles in the hydrogen-rich bath water can be collected and recycled to the drainage pipe 403, so that the large hydrogen bubbles re-enter the ejector 4. At the same time, the recycled hydrogen bubbles are supplemented into the drainage pipe 403 of the ejector 4 as a new source of hydrogen, thereby increasing the amount of hydrogen entering the water-gas mixer 3, further improving the hydrogen content in the hydrogen-rich bath water, and helping the hydrogen-rich bath water to exert its therapeutic effect.

[0039] In specific applications, a hydrogen absorption device 11 for hydrogen absorption by human body can be connected to the exhaust port of the gas-liquid separator 2 through a pipeline, that is, a part of the hydrogen discharged from the exhaust port of the gas-liquid separator 2 is used to be recovered to the drainage pipe 403, and the other part is used to be provided to the hydrogen absorption device. The hydrogen absorption device 11 includes a mixing container 1103 with a suction fan 1107 built in. The mixing container 1103 is provided with an air inlet pipe 1105 connected to the exhaust port pipeline of the gas-liquid separator 2, an air pipe 1104 for providing air to the mixer 1103, and an exhaust pipe 1108 for discharging the gas mixed by the mixer 1103 for hydrogen absorption by human body. The exhaust pipe 1108 is provided with a hydrogen concentration sensor 1100 for detecting the hydrogen concentration in the discharged mixed gas. 2. In specific implementation, the suction fan 1107 can be a micro fan, which not only provides transportation power for hydrogen absorption, but also can stir the air and hydrogen entering the mixing container 1103 to accelerate the mixing of the gases. The air pipe 1104 and the air inlet pipe 1105 are arranged at one end of the mixing container 1103, and the exhaust pipe 1108 is arranged at the other end of the mixing container 1103. The air inlet pipe 1105, the exhaust pipe 1108 and the air pipe 1104 are all provided with a flow regulating valve 1101. A desiccant 1106 for drying the air and hydrogen entering the mixing container 1103 can also be provided in the mixing container 1103 to improve the dryness of the gas entering the human body when the human body absorbs hydrogen. A hose 12 for facilitating hydrogen absorption by the human body can also be provided on the exhaust pipe 1108.

[0040] When the suction fan 1107 is started, air and hydrogen enter into the mixing container 1103 and mix. Specifically, each flow regulating valve 1101 can be adjusted so that the concentration of hydrogen in the mixed gas discharged from the exhaust pipe 1108 is between 2% and 4%. The user can use the hose 12 to absorb hydrogen. At the same time as using hydrogen-rich bath water, hydrogen can also be appropriately absorbed. Compared with only using hydrogen-rich bath water for health preservation, the combination of hydrogen-rich bath water and hydrogen absorption can enhance the efficacy of the whole device on human respiratory diseases.

[0041] Furthermore, a degassing tank 8 is provided on the pipeline between the ejector 4 and the water tank 6, and a vacuum pump 7 for maintaining the vacuum degree of the degassing tank 8 is provided in communication with the degassing tank 8, that is, the degassing tank 8 is evacuated by the vacuum pump 7, and after the water enters the degassing tank 8, the dissolved gas in the water escapes from the water body under the action of the vacuum, and the dissolved gas flowing through the water is removed. After the gas in the water provided by the water tank 6 is removed by the degassing tank 8, the water flows into the ejector 4 along the degassing water pipe 801. Specifically, the water inlet of the degassing tank 8 is connected to the water tank through the water supply pipe 602, and a spraying system and corresponding fillers can be arranged in the degassing tank 8 to make water spray and fall, so as to facilitate the escape process of the gas in the water under the vacuum state. A vacuum pressure gauge and a corresponding valve are provided on the degassing tank 8, and the water outlet of the degassing tank 8 is connected to the nozzle 405 of the ejector 4 through the degassing water pipe 801. Booster pump, according to Henry's law, since the dissolved gas in the water is removed by the degassing tank 8, the hydrogen delivered by the hydrogen generator 5 is not only easier to dissolve into the water body, but also increases the amount of hydrogen dissolved. In addition, the gas removed by the degassing tank 8 itself occupies a certain amount in the water body, such as the dissolved oxygen in the water. The setting of the booster pump makes the water in the degassing water pipe 801 have pressure. Under the pressure, when the pressure reaches a certain level, the gas molecules of dissolved oxygen will affect the dissolution of hydrogen, that is, under the pipeline pressure, the gases dissolved in the water will affect the dissolution of other gases due to the interaction between gas molecules. When the degassing tank 8 removes these gases such as dissolved oxygen, the intermolecular interaction between other gas molecules such as dissolved oxygen and hydrogen gas molecules is avoided, thereby increasing the dissolution of hydrogen in the water, and further increasing the amount of hydrogen dissolved in the hydrogen-rich bath water.

[0042] Furthermore, a circulating water pipe 802 is provided between the degassing tank 8 and the water tank 6, through which the water body can be vacuum degassed multiple times, thereby improving the degassing quality of the water entering the ejector 4, so that the dissolved gas contained in the water to be mixed with hydrogen is reduced to the minimum. As mentioned above, when the dissolved gas in the water to be mixed with hydrogen is further reduced, the amount of soluble hydrogen in the water will increase, thereby further increasing the amount of dissolved hydrogen in the hydrogen-rich bath water.

[0043] When implementing the present invention, the hydrogen generator 5 can be a device for storing hydrogen, such as a high-pressure hydrogen cylinder. However, when the gas provided by the device for storing hydrogen enters the injector 4, it is easy to cause the phenomenon of bubbles being too large. The hydrogen generator 5 of the present invention can produce hydrogen by electrolysis. Specifically, the hydrogen generator 5 includes a box-type or cylindrical electrolytic cell 501 and a DC power supply 510 arranged outside the electrolytic cell 501. The DC power supply 510 can be a constant voltage power supply or a constant voltage and constant current DC power supply. The electrolytic cell 501 is provided along the middle of the cell body to divide the electrolytic cell 501 into a cathode region 504 and an anode region 506. The proton exchange membrane 505 used in the embodiment of the present invention is a DuPont 117 perfluorosulfonic acid proton exchange membrane. Other proton exchange membranes 505 may also be used. A cathode region 504 is provided with a negative electrode 502 connected to the negative circuit of a DC power supply 510. An anode region 506 is provided with an anode electrode 508 connected to the positive circuit of the DC power supply 510. Both the anode region 506 and the cathode region 504 are provided with a water inlet 509 and a water outlet 503. The water outlet 503 of the cathode region 504 is connected to the drainage pipe 403 through a water outlet pipe 512. A hydrogen discharge water pump 514 is provided on the water outlet pipe 512.

[0044] By producing hydrogen through electrolysis and directly transporting hydrogen with water, a hydrogen gas source is formed that uses water as a carrier to transport hydrogen, so that hydrogen bubbles are taken away by the flowing water flow just after they are precipitated and formed at the cathode 502, reducing the aggregation of hydrogen bubbles, and producing small-diameter hydrogen bubbles by electrolysis, reducing the generation of large-diameter hydrogen bubbles, which is beneficial to the further refinement of bubbles in the water by the water-gas mixing device 3. In addition, compared with the previous static water electrolysis hydrogen production, there is a concentration difference between hydrogen ions on the surface of the cathode 502 and in the water body, which easily causes a slow diffusion rate of hydrogen ions and the occurrence of concentration polarization. In the present invention, flowing water is used for electrolysis, which can not only quickly take away the small hydrogen bubbles precipitated on the surface of the cathode 502, but also accelerate the diffusion of hydrogen ions in the water, avoiding the occurrence of concentration polarization on the surface of the cathode 502, thereby increasing the speed of hydrogen production.

[0045] Specifically, during the hydrogen evolution reaction on the cathode electrode 502, the metal ions on the electrode surface are first combined with hydrogen ions through an electrochemical reaction, and then the hydrogen ions are released through desorption. Finally, the hydrogen ions are combined with the hydrogen ions to form hydrogen molecules. In the hydrogen ion adsorption process, both the cathode electrode 502 and the anode electrode 508 can use plate-shaped or rod-shaped platinum electrodes. When using platinum electrodes, since the current density of the adsorption bond strength of the platinum electrode is the highest, it is more conducive to the combination and desorption process of metal ions and hydrogen ions in the hydrogen evolution reaction, thereby increasing the speed of hydrogen production by electrolysis. In order to save production costs, the electrodes can also be made of other materials, such as nickel-plated iron electrodes.

[0046] Furthermore, the surfaces of the cathode electrode 502 and the anode electrode 508 are uniformly distributed with thorn-like structures. The thorn-like structures can be mechanically grooved to carve a plurality of closely adjacent V-grooves on the surface of the platinum electrode. The depth of the V-grooves is about 30-60 microns, so that the electrode surface is uniformly distributed with the thorn-like structures. The thorn-like structures can also be prepared by other methods. Specifically, the thorn-like structure part can also be made into a porous structure to increase the specific surface area of ​​the electrode, which is beneficial to the cathode hydrogen evolution reaction. By arranging the thorn-like structure on the electrode surface, the relatively smooth electrode plane is more conducive to the separation of hydrogen bubbles from the contact surface with the electrode, reducing the aggregation of hydrogen bubbles on the electrode surface, and further facilitating the generation of small-diameter hydrogen bubbles, which helps to finally prepare hydrogen-rich bath water containing hydrogen bubbles with smaller diameters.

[0047] Furthermore, a circulating hydrogenation pipe 513 is provided to the water outlet pipe 512 and the water inlet 509 connecting the cathode area 504. When the hydrogen content of the water in the water outlet pipe 512 is low, the solenoid valve provided on the circulating hydrogenation pipe 513 can be opened to inject the water in the water outlet pipe 512 back into the electrolytic cell. After circulating in the electrolytic cell for several times, the hydrogen content is increased.

[0048] In a specific implementation, the water inlet 509 can be connected to the degassed water pipe 801 through the water inlet pipe 511, and the degassed water is used as the source of water in the electrolyzer. As mentioned above, after the dissolved gas in the degassed water is removed, when it comes into contact with new gas, it is beneficial for the gas to dissolve into the water body. In this way, when hydrogen is produced by electrolysis, the hydrogen precipitated on the surface of the cathode electrode 502 can dissolve into the water more quickly, making it easier for the hydrogen bubbles to overcome the surface tension and break away from the surface of the cathode electrode 502 and enter the water body.

[0049] Specifically, the water outlet of the anode area 506 can be connected to the water tank 6 through the return pipe 507, which is convenient for recycling electrolyzed water. A water replenishment pipe 601 for replenishing the water source can be provided on the water tank 6. Since the recycled water contains oxygen generated by the electrolysis of the anode electrode 508, the water replenishment pipe 601 can be used as a pipeline for exhaust when no water replenishment is required.

[0050] Furthermore, the water inlet pipe 511 is provided with a heat exchanger 10 for increasing the water inlet temperature of the electrolytic cell 501. The heat exchanger 10 can be a plate exchanger. The water entering the electrolytic cell 501 is used as a cold source. The heat exchanger 10 is connected to a constant temperature water bath device 9 for providing constant temperature hot water to the heat exchanger 10. Specifically, a flow meter 901 is provided on the pipeline for the constant temperature water bath device 9 to transport the heat source to the heat exchanger 10. The constant temperature water bath device 9 can be a constant temperature heater. The constant temperature water bath device 9 provides a stable heat source for the heat exchanger 10. After the water entering the electrolytic cell 501 passes through the heat exchanger 10, the water temperature is increased and has a certain constant temperature effect. After entering the electrolytic cell 501, the transfer and diffusion of hydrogen ions in the electrolysis process can be effectively increased, thereby increasing the speed of hydrogen production by electrolysis.

[0051] In addition, when producing hydrogen by electrolysis, a certain amount of additives can also be added to the water tank 6 to enhance the conductivity of the water and increase the speed of hydrogen production by electrolysis. However, it should be noted that the additives added to enhance the conductivity of the water should be harmless to the human body and should not affect the electrolysis process of hydrogen production by electrolysis.

[0052] It should be noted that corresponding booster pumps, pipeline valves and related meters can be added to some pipelines in the present invention according to application requirements, and three-way valves can be used to connect pipelines. This is a choice that technical personnel in this field can make according to production needs and will not be specified here one by one.

[0053] It should be noted that the parts not described in detail herein are prior art, and the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
